The latest ZR1 leaves two black rubber stripes all over the supercar rulebook
One is never short of finding superlatives to describe the new Corvette ZR1, such is its unapologetically raw, sometimes uncouth, nature. It’s a bare-knuckle brawler that takes dead aim and leaves destruction in its wake. That’s the way it’s always been for the ‘Vette; the underdog and the American hero. Its mantra: To do the most, and often with the least.
The latest version attempts to stay relevant amid its supercar contemporaries without subscribing to a mix of hybrid powertrains and heavy all-wheel drive systems. That launches it down a unique path and ensures it appeals to a very certain type of buyer. The goal was to extract the most power as possible with the revised LT7 5.5-litre turbocharged engine making 793 kW (1064 horsepower), every day and all the time. No cool down process or recharging required. For a fun comparison, the ZR1 launched in 1990 made 280 kW (375 horsepower) – identical to that of the Ferrari 355 which costs significantly more.
That question however was never about how much power it could make, but rather how effectively it could put that power down to the rear wheels. The on-board tyre temperature gauge is your best friend in this regard, letting you know when the Michelin Pilot Sport Cup 2R tyres might have a glimmer of hope of finding grip.
More often than not you’re tentatively tickling the baby toe of the 5.5-litre twin-turbo engine. Sometimes that feels like a shame given just how much work has gone into redesigning it, creating new heads, shortening the conrods, changing the compression ratio so that a pair of 76 mm turbos can force the air in at 186 kPa, while the 16 injectors try and keep up with a consumption rate of 7.6 litres (two gallons) per minute.
Get it hooked up with the quite nerdy launch control – it’s not a one-size fits-all but instead offers some adjustability so you can dial in some slip – and the 0-97 km/h comes up in 2.3 seconds with a top speed of 375 km/h. That latter’s not some hypothetical claim either; recently General Motors President Mark Reuss drove a 2025 Corvette ZR1 to 375 km/h, setting a top speed record unrivalled by any current production car priced under $1.52 million.
Peak torque arrives at 3000rpm and although turbos this large would benefit the most from some form of electric torque fill, the new engine keeps them fed and on song well past 7000rpm. The turbos are fitted with sensors and this information is constantly relayed to the engine management so that it can make adjustments and keep them whizzing at optimal speeds.
Contrast this for a second with the Corvette E-Ray which uses a 6.2-litre LT2 Small Block V8, putting out 359 kW (482 horsepower) and 613 Nm of torque to the rear axle. It is complemented by an electric motor that channels an additional 120 kW (161 horsepower) and 165 Nm (121.7 lb-ft) of torque through the front wheels via a 1.9 kWh battery pack. That combined setup can achieve 0-97 km/h in 2.9 seconds without destroying entire forests as you drive by.
Back to the engine of the moment. It’s worth mentioning that it’s now mid-mounted for obvious traction performance. Less obvious is that the engine is so wide that it couldn’t possibly fit in the nose and still allow for enough steering geometry. That space in the front has also shrunk by virtue of the additional coolers that have been fitted. Another upside is that the smaller frontal area helps slice through the air, even if the engine would have no trouble moving a small seaside town. Fortunately, the absence of electric motor and batteries means it travels relatively light at 1724 kg with each kilowatt only needing to push 1.6 kg. Bringing it back to a stop are new front rotors measuring 399 mm in diameter and rear rotors 391 mm in diameter — the front rotors are the largest ever equipped on Corvette. In just 24.5 seconds, the Corvette ZR1 goes from 120-300 km/h and back to 120 km/h — 22% quicker than the C7 Corvette ZR1, and 53% quicker than the C6 Corvette ZR1.
Its rivals can include exotics like the Ferrari F8 and upcoming Lamborghini Tremerio. That means the ZR1 needs to excel across a gamut of situations, not just straight-line duels. Cue then the aero. A Carbon Fibre Aero package, costing $12,912 (approx. $8,495 USD), includes the dominant rear wing as well as dive planes and a larger rear spoiler in front. The rear wing obscures almost every fraction of rear visibility but is forgiven for the 544 kg of downforce it generates, or a 33 per cent improvement over the Z06. The rear-view camera has never been so necessary!
There’s no DRS mode but its drag levels at loftier speeds is believed to be relatively negligible. And with the engine no longer in the direct path of incoming airflow, several other solutions in the form of ducts and venting had to be carved into the bodywork, adding a level of aggression in the process. It gives the designers over at Sant’Agata a few sleepless nights, yet retains its own identity with subtle throwbacks to the proud lineage with features such as the split rear window.
There is also the $2,280 ZTK package, on top of the Aero package. This brings stiffer springs, Michelin Pilot Sport Cup 2R tyres in place of the standard Pilot Sport 4S rubber, and unique calibration to electronics systems like the magnetorheological dampers and electronic differential.
Typically you climb into a Corvette’s cabin with a sense of inevitable dread. The proverbial crash after a sugar high. They just don’t feel as well executed, or intuitive compared to a modern Ferrari or Porsche. And although it isn’t perfect, that wide centre stack does have its own peculiar charm with the way it beams information right through your eye sockets and is so utterly driver-focused you might forget about your passenger.
A new makeover is expected soon which among other things removes the wall of buttons between the seats and installs a trio of screens, all still angled towards the driver. Not only does it look better, it adds more functionality like wireless charging, more smartphone support and new interior lighting.
Since the ZR1 was always part of the original plan, pricing hasn’t suffered like it would if a whole bunch of new bespoke chassis and engine parts needed to be engineered.
No all-wheel drive system or exotic lithium-ion batteries also keeps the cost down. At $270,856 (approx. $178,195 USD), it goes up against quite ordinary Porsche 911s yet offers so much more theatre and rarity, even if several markets outside the United States, Australia included, won’t ever have the chance to experience it. ■
